Circuit/System Description
The steering angle sensor receives a 12 V reference voltage
from the electronic brake control module (EBCM). The EBCM receives
high speed controller area network (CAN) message inputs from the
steering angle sensor identifying the position and direction of the
steering wheel rotation. The EBCM utilises this signal to calculate
the driver intended driving direction.
Conditions for Running the DTC
Ignition ON.
Conditions for Setting the DTC
C0460 71
The control module received an invalid steering angle sensor
signal.
C0710 00
The steering angle sensor signal is invalid
C0710 42
The steering angle sensor is not calibrated.
C0710 5A
| • |
The steering angle sensor signal is out of
specified range. |
| • |
The steering angle sensor offset is out of
specified range. |
C0710 71
The steering angle sensor signal is not plausible with the yaw
rate sensor signal and lateral acceleration sensor signal.
Action Taken When the DTC Sets
| • |
The EBCM disables the stability control for the
duration of the ignition cycle. |
| • |
The traction control/stability control active
indicator turns ON. |
Conditions for Clearing the DTC
| • |
A current DTC clears when the diagnostic runs and
passes. |
| • |
The EBCM will turn OFF the indicator in the next
ignition cycle. |
Diagnostic Aids
The car should not pull in either direction causing the steering
wheel to be OFF centre while driving in a straight line on a level
surface.

Circuit/System Verification
Ignition ON, observe the scan tool Steering Column Position
parameter. As the steering wheel is turned, the reading should
travel from -550 to +550°.
Circuit/System Testing
- Ignition ON, verify that DTC C0710 is not
present.
- Inspect the B99 Steering Wheel Angle Sensor for
correct installation.
- Ignition OFF, key out, open and close the driver door,
wait 60 s, disconnect the harness connector at the
B99 Steering Wheel Angle Sensor.
- Test for less than 10 Ω between the ground
circuit terminal 6 and ground.
| ⇒ |
If greater than the specified value, test the
ground circuit for an open/high resistance. |
- Ignition ON, within 5 s test for greater than
11 V between the 12 V reference circuit terminal 5
and ground.
| ⇒ |
If less than the specified range, test the
12 V reference circuit for a short to ground or an open/high
resistance. If the circuit tests normal, replace the
K17 Electronic Brake Control Module. |
- If all circuits test normal, replace the
B99 Steering Wheel Angle Sensor and verify the DTC does not
reset.
| ⇒ |
If the DTC resets, replace the K17 Electronic
Brake Control Module. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
